Pepper Posted September 11, 2022 Share Posted September 11, 2022 Hello. I picked this up the other day thinking it was wood, but on a closer look I could see webbing, with a bone like structure, however it is really worn. Would anyone have an idea on what it may belong too if it is indeed a bone? Found in a Cretaceous beach site, South Island, New Zealand. Many thanks in advance.

Rockwood Posted September 11, 2022 Share Posted September 11, 2022 With apologies to the chunkasaur folks, this looks like a bob to me. (blob of bone) 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 11, 2022 Share Posted September 11, 2022 I think it is too worn to say more than fossil bone. 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

"really worn" is relative. How worn can a bone get on a beach across 66 million years? I have numerous bones from Florida from 10 mya that do not have this level of detail. It is a bone.. When I have nothing else, I think about form and function... This bone may have been broken a thousand times over the eons and have zero resemblance to the original bone it came from... ot then again it may not.. Your fossil is round , small, flat....., I have found some like that...

Absolutely, but the only other fossils that I could think looked somewhat similar and are of similar sizes are sesamoid bones, and I could not track down a photo example. Please do not mis_interpert. I am not implying that Pepper's find is an epiphysis, just that an epiphysis (and some sesamoids) have form/size similarities. Pepper's find is almost certainly not identifiable. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Brandy Cole Posted September 11, 2022 Share Posted September 11, 2022 I agree it's not identifiable. It looks like all that's left are worn edges. Without any clear cortical bone or articulation surface visible, it's impossible for me to get an idea of what the original shape would have been, especially since it was found on a beach and water wear naturally rounds and flattens items. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted September 11, 2022 Share Posted September 11, 2022 Trampling of bones at any stage of the taphonomy would provide a good start to the process. 1 Link to comment Share on other sites More sharing options...

Thanks for your reply I have quite a collection from a very special site that represents a mid to late Cretaceous continental shelf - high latitude paleoenvironment. There is also a stream that carries decent sized fossilised wood pieces from further inland that become strewn along the beach. That piece of bone is worn compared to the other bones I have found on the beach (without any matrix). I have supplied some fossils I have found including marine reptilian vertebrae and just a very small portion of the wood I have collected over a couple of years. 1 Link to comment Share on other sites More sharing options...

It seems like you have a magic place where you can seek solitude and renourishment while collecting the gifts of nature. Many on this forum are equally blessed, including myself. We hunt in different environments. Mine tends to be the last 15 myas, but it is more than sufficient. Is this one of your "marine reptilian vertebrae" ? I could see myself finding something very much like it. But, given the enormous distance in space and time, they could not be the same...
